Buying Property at Auction Advice

[Alex Babayev]

Hello, 

I am planning to go and bid at the courthouse steps for a couple properties I am interested in. I have never done this before, previously I have bought regular short sale, foreclosure proeprties that have gone through a traditional closing process. 

I wanted to get advice on some proper precautions to take. Meaning how do I know if the property has contractor liens, unpaid utilities or any other debt attached to the property?

Is there a service I can hire to tell me this type of information? So I can price this extra expenses into my bidding price. 

Thanks in Advance.
